It takes a lot for a single person to pull attention away from a heavy metal band. When you see this woman's passion, you'll understand why all eyes were on her.

Lamb of God is one of the supporting acts on Slayer's farewell tour. To help out the hearing impaired in the crowd, they've hired a production company that specializes in American Sign Language interpretation.

The woman featured in the video is seen wearing all black and does more that just sign the lyrics being sang (roared?). She throws herself into the performance and produces the same amount of energy being put out on the stage behind her.

The ASL interpreter mimes the screeching vocals while providing air drums and guitar.
